A DHCP relay agent is any device that forwards DHCP packets between a client and a DHCP server. Cisco routers can act as DHCP relay agents and the way you tell them to do this is to configure the "ip helper-address " under the router interfaces.

So the ip helper-address is simply the way Cisco implements the DHCP relay function on it's routers.
